VOTING-MACHINE.

SPECFICATION 'forming part of Letters Patent No. 620,417, dated February 2s, 1899.

Application filed May 26,1897. Serial No. 638,257. (No model.)

`T0 ctZZ whom t may concern:

Beit known that I, JOHN F.. OHAPIN, a citizen of the United States, residing at North Fork, in the county of Madera and State of California, have invented certain new and useful Improvements in Voting-Machines; and I do hereby declare that the following` is a full, clear, and exact description thereof.

My invention relates to machines forenabling voting to be done mechanically; and my object is to produce a connected mechanism which will commence and continue to register automatically the successive votes for a series of candidates on different political tickets.

My object is further to provide means for printing the footings or totals of votes cast for each and every candidate at the end of the election, so that all counting of votes can be done away with. The machine is hence a combined voting and vote-counting device,

' by the use of which the result of the vote in any precinct can be known with mathematical correctness immediately at the close of the voting, all the names and totalsV being recorded upon a slip by a printing mechanism, forming part of the machine, and brought into use after the vote-registering devices have completed their work.

I have embodied my invention in a mechanical structure which fully illustrates its construction and operation and which is fully hereinafter described and is shown in the drawings accompanying this specification.

In the drawings, Figure l is a front elevation of the machine with the shell broken away in parts. Fig. 2 is an end elevation showing the driving-gearing for the recording device. Fig. 3 is an opposite end elevation.l Fig. 4- is a plan view of the mechanism shown in Fig. 3. Fig. 5 is a central vert-ical section of Fig. l. Fig. 6 is a detail View of one of the push buttons or studs and the mechanism directly connected to it for numbering the votes. Fig. 7 is an enlarged detail elevation of part of Fig. l. Figs. 8 and 9 are details of two of the numberiugdisks. Figs. 10 and 11 are detail views to illustrate the operations of the hand and automatic latches for 'locking and releasing the rotary voting mechanism.

The apparatus is shown as supported by a frame A, in the upper part of which is journaled a shaft B. This shaft is intended to be turned automatically but intermittingly during the process of voting, by which I mean that such shaft is under the control of the voter so far as permitting it to start after e B2, having a series of notches 2, formed in a flange 3, projecting from said disk, Figs. l and 4. As many of these notches are provided as there are oiiices to be filled upon the different tickets.

E, Figs. l, 3, and 4, isa spring-arm provided with a handle and secured to a sleeve 4., loose on the shaft B aud just outside the end frame of the machine. The arm Eis a spring-latch by reason of its tooth 5, which has a beveled upper surface and which tends to engage by the spring action of said arm with the edge of the disk B2 or one of the notches 2 in such edge. This latch E is the means by which the voter controls the starting of the machine after each automatic stoppage. It must be understood that the shaft B is run by a motor for a full revolution, during which a number of votes are cast or registered, but that such shaft is stopped while the votes are being cast. If` this latch E is in engagement with a notch 2, the shaft cannot start. Hence the voter positively disengages the latch from the notch, and the machine commences vto operate, the latch riding on the plain edge of the disk B2 until it springs into the next notch and stops the machine. This would produce an automatic stoppage of the machine unless the voter accidentally. or intentionally held out the latch E until the next notch or any number of notches had passed, and as it would be in his power to so hold out the latch the machine might make its full revolution without stopping and without any votes having been cast. I therefore provide a second and completely-automatic spring-latch E, which is secured to and concealed under the inclosin g shell A2, which covers the operative mechanism, Figs. 1 and 3. This latch E is a spring-arin having a tooth which always tends to engage the notches 2 and will do so if the latch E shall have been held out. This safety or automatic latch can, however, be disengaged by the beveled tooth of the latch E, as shown in Fig. 1, after it has stopped the machine. The voter can therefore control the release of the latch E', but he cannot prevent its engagement without engaging the latch E,which produces the saine result. This operation will be more clearly understood by referring to Figs. 10 and 11. The tooth 5 of latch E is not so wide as the notch 2 or as the tooth 6 of latch E. When the latch E is engaged with the notch by hand, it lifts latch E@ Means hereinafter described for revolving the shaft and voting-disks act at once, causin0i the wall of the notch to bear against tooth o, Fig. 1l, so that latch E rides upon the plain face of flange 3 and remains there until it falls into the next notch after the voter has released latch E, Fig. 10. From this it is released by the entering beveled tooth of the liaiid-latcli, so that the parts again assume the position of Fig. 11.

The voting is done by pressing successive push-buttons, each of which is connected to a numbering and counting attachment. These push-buttons are carried around by the rotation of the main shaft and disks, so that a single rotation enables the whole ticket to be voted or parts of different tickets. These devices will be fully described; but in the first place l wish to describe a particular mechanism for rotating the shaft, to which, however, I do not limit myself, since other means of imparting motion may be employed. My device, however, lias the merit of simplicity and of being driven by a power which exhausts itself while a person is voting and is renewed and then exhausted automatically by his successor. I prefer this means to any constantlyrunning motor, which is liable to break down or become finally exhausted before the days voting is finished. In describing this meehanisni l refer particularly to Figs. 3 and 4 in connection with Fig. 1.

lVhen a voter enters the polls and approaches the machine to vote, he steps upon a hinged platform F, pivoted at the edge of an opening in the main flooring. To this hinged platform is pivoted arod 7, connected to a lever S, having a bearing upon a pin Sl, projecting from the main frame. The lever is loose upon the pin, and a coil-spring 1 is interposed between it and a collar 10 on the end of pin 9, Fig. e. A tooth 11 projects sidewise from the lever, which engages with a recess 12 in the hub of a quadrant 13, journaled on the pin 9. A depression of lever 3 will raise the quadrant 13 until a beveled projection 1t on lever 8 strikes a small fixed pin 15 on the frame and forces the lever outtoward the end collar 10. This action is timed to occur as the hinged iioor reaches a horizontal position, at which time the lever 8 becomes disengaged from the recess in the quadrant, and as the quadrant immediatelycommences to move in the opposite direction (as will be presently explained) the tooth 11 rides on the face of the hub until the recess comes again into position to allow the tooth 11 to snap into it. The first motion of the quadrant, produced by standing on the hinged floor, is to wind up the weight F, which is the motive power for creating a single revolution of the main shaft and voting-disks. To accomplish this, the quadrant gears into a pinion 16, loose on the main shaft and formed in one part with a drinn 17. A ratchetwheel 1S is fixed on the end of the shaft and engages a pawl 10, carried by the drum. The motion of the pinion and drum winds up the coi'd of the weight FC The runnin g down of this weight communicates motion to the ratchet-wlieel, shaft, and voting-disks, which motion is automaticallystopped bythe latches before described. The voter on approaching the machine steps upon the movable platform and depresses it, winding up the weight. Should he step olf the platform and return to it, no effect is produced upon the mechanism, since the shaft must make a complete revolution before the lever connected to the weight can again engage with the liftiiig-quadraiit. The weight causes the shaft to turn, the latch E having been disengaged by the voter. The disk B2 will hence be moved a distance equal to the space between two of its notches 2, when it will be stopped by the latch E snapping back into the next of such notches. Should the voter hold out the latch E, the latch E' will automatically stop the disk and shaft and must then be disengaged by pushing the latch E under it and into said notch, as before described. The mechanism thus far described for moving the shaft and disks intermittingly might be dispensed with, since it is evident that a liaiid-pull on the latch F. would produce the same effect in connection with the latch E, acting as a stop; but l prefer to use the weight or some equivalent power, because it makes the machine more nearly automatic and leaves less to be done by the voter.

The voting-disks C C' D D' have been already mentioned as mounted on the shaft and moving with it. Each pair of disks, representing a party-ticket, carries a number of registering and counting wheels bearing the numerals from l to 0, inclusive, and arranged preferably in sets of three, so as to count into hundreds, which is an ample range for ordinary precinct use. ln the drawings eight of these registers are shown to each pair of disks, representing eight candidates npon each of two tickets. Secured to each disk is a series of eight cylinders Il, each having a sliding push-button ll', the stein 2O of which has a spring 21, which tends to force it outward. The stem is connected by a slotted crank 22 to the central shaft 23 of the appropriate units-wlieel Il?. Figs. C and 7 show this IOO IIO

connection clearly. Hence a depression of any button will revolve the units-Wheel the dis,- tance from one numeral to the next. The construction of this wheel is shown in Figs. 8 and 9, which figures represent opposite elevations of it, Fig. 3 showing its right-hand face (as looked at in Fig. 7) and Fig. 9 its left-hand face in the same figure. An arm 24 is liXed upon the shaft 23, which carries a spring-pressed pawl 25, adapted .to engage with ratchet-teeth 2G, formed upon the face of Wheel H2 and having notches 27 at their base. All the wheels of the series are loose upon a slotted sleeve 28, the slot 29 of which is wide enough to give the arm 24 a sufficient range of movement as the shaft 23 is rocked by the pressure and release of the push-but ton. When the button is pushed in, the pawl 25 moves in the direction of the arrow, Fig. 3, and turns Wheel H2 a distance equal to one tooth of the ratchet 26. A collar 30, slightly eccent-ric at 3l, is fixed upon the sleeve 28, grooves 32 being formed in said sleeve to receive feathers 33 on said collar. The pawl 25 in moving theratchet rides' upon the edge of collar 30 until the eccentric 3l lifts it from a notch 27 at the end of its stroke. On the release of the push-button the pawl 25 moves back and seizes the next tooth of the ratchet. Fig. 9 represents the opposite side of the same Wheel and shows the connection between the units-wheel H2 and the tens-Wheel H3. An arm and pawl 34, similar to pawl 25, is secured upon shaft 23 between the two wheels. On the units-wheel is an other ratchet 135, which has but a single tooth 136, upon which the pawl 34 rides until it can engage with said tooth, such engagement permitting it to engage at the same time with a ratchet on the tens-Wheel exactly like the ratchet 26, before described. with a disengagingeccentric 137, like that shown at 3l. The pawl 34I can hence move the wheel H3 but once for ten movements of the wheel H2. The connection between the tenswheel and the hundredswheel is .precisely similar and operates in the same way. Above the main frame is secured the shell or cover A2, which protects the mechanism from inspection and prevents any tampering with the registers. As the main shaft and voting-disks stop at proper intervals, as before described, each button is displayed `opposite a slot J in this shell, together with a name-plate K, secured to the disk and bearingin letters the name of a particular person and of the oliice for which he is a candidate. These buttons may be operated by the finger-sof the voter directly; but I prefer to `use pivoted levers L, one for each series of buttons and registers, and having a stud L', which is brought to bear upon the successive buttons as they are displayed. The voter holding this lever in one hand and the latch E in the other has only to move the latch from one notch and then press the button,

The sleeve is providedv in g-slot.

when the machine stops at the next notch. This registers a vote on the nu mberin g-Wheel appropriated to that oiiice, candidate, and ticket. He continues the same proceeding until the machine has made its full revolution, during which he has seen displayed the names of all candidates and all oiiices on all tickets and has voted for as many as he has desired to do, the machine having while at rest displayed each ofiice and candidate in succession and all the ditlerent candidates for the same office at the same time. The registers are automatically counting the successive votes until when election is over each set of registers shows the total of votes cast for a particular candidate.

In order to lock the push-buttons and prevent repetitions of a Vote cast by means of any one of them, I have devised certain automaticlocking mechanism. (Shown in Fig. 1 andin full detail in Figs. 6 and 7.) Extending through holes in all the voting-disks are sliding tubes M, having oppositely-placed slots 35 and 36 and provided with pressure-sprin gs 37, which tend to force them constantly toward the end of the machine. (Shown in Fig. 7.) As many of these tubes are provided as there are push-buttons for each disk, there being eight shown in the present case. Adjacent l to each tube and also held loosely'in bearings in the votingdisks is a rock-shaft N, carrying a latch 38 and acted upon by a torsion-spring 39, coiled upon said rock-shaft and secured to an adjacent disk. The tendency of spring 39 is to cause the latch to engage with the short slot 35, Fig. G. The stems of all the push-buttons adjacent to one of these tubes project through the long slot 36 and int-o the tube. In the normal position of these parts and eX- cept while a vote is being registered the slot 35 is out of line with the stem of the pushbutton and with the latch 38, the spring 37 having pushed the tube toward the end of the machine. Pivoted to the end frame of the machine is a cam 40, against which the projecting end of each tube M bears once in each rotation of the disks. This cam forces the tube inwardly until the latch 38 can snap into slot 35, Fig. 6, and lock the tube. The slot is somewhat longer than the Width ofthe latch, and the latch is somewhat wider than the stem of the push-button, Fig. 7. The disk stops with the push-button opposite the vot- When the voter presses the button, its stem enters the slot 35 and pushes the latch out of the same. The slight difference in Width between the stem and latch allows the tube to be moved slightly to the position of Fig. 7 so that When the button is released the latch 33 is held out of the slot 35 and the tube is forced by its springs 37 back to its normal position, so that it strikes the cam again on its next revolution. This takes place simultaneously with the release of the button, and hence no second pressure by the same voter can occur, the stem being noW locked ICO by the solid wall of the tube and remaining locked until the next revolution causes the cam to unlock that button.

At the close of the voting each register indicates the full number of votes cast for a certain candidate and the push-buttons are all locked, The election officers now prepare to record the vote by printing the names and totals upon a paper strip, and this is done by the machine by mechanism which hitherto has not come into operation. In the first place the cam a0 is moved upon its pivot il, so as to be out of the path of the tubes in order that the push-buttons cannot possibly be unlocked and operated while the recording of the vote is being done. The recording devices are best shown in Figs. 2 and 5. The counting-wheels and the name-plates adjacent to them carry upon rubber strips or otherwise numbers andnames in negative relief from which a positive print can be made.

The printing mechanism is operated by giving a single rotation to the main shaft, disks, and locked counting-wheels, which causes such wheels to print off their totals through an ink-ribbon O, or by being inked themselves upon a strip of paper P. The ink-ribbon shown and the paper strip are carried by rollers beneath the voting mechanism, which are driven by gearing, as shown in Fig. 2. On the main shaft is a large gear Q, adapted to be engaged by a pinion R of the train R R/ R2. These pinions are journaled in bars S S' S2, pivoted at their forward ends to the main frame and having their rear ends adjustable in said frame by means of slots 4:2, which receive pins a3, projecting from said bars. The bars are also connected by a crossbar S3, which causes them to move simultaneously. An eccentric T is fixed upon a shaft 4i, journaled in the main frame at its rear, by turning which the pinion R can be either engaged or disengaged from the driving-gear. During the operation of voting the train of gears is idle. The ink-ribbon is shown as running upon three rollers U U2 U3, the former being upon the shaft of gear R and the others being journaled in the bars S and S2. The paper strip is also carried by three rollers U' V V' and is shown as wound upon the roller V and adapted to be wound from that roller upon the roller V. The ink-ribbon and paper strip move in the same direction across the roller U' toward the rear of the machine. lVhen the counting-wheels are locked and the gears engaged, a single revolution of the main shaft will cause every wheel and name-plate to strike the ink-ribbon above the paper strip on the roller U' and to impress upon such paper strip the names and totals of all the votes cast.

It is obvious that at any time during the election, if required to do so, the election oliicers can stop the votingfor a few minutes and record the progress of the voting up to that time by giving the shaft a revolution with the gears engaged and the countingwheels locked.

As a precautionary device to prevent a voter from allowing the machine to make asecond revolution and so voting twice I have devised a safety-catch XV, which automatically locks the driving-shaft and disks after cach revolution. This catch is pivoted in the main frame and is pulled by a spring 47 into engagement with a stud AS on one of the votingdisks, which it locks against movement in either direction. An arm W",havinga hooked end, is pulled bya spring 49 into engagement with a stud O on the catch XV. The arm W is connected to the hinged platform. At any convenient point on said arm is formed an incline 5l, which when the platform is depressed acts as a cam against a fixed pin 52 on the main frame. In the operation of these connections the movement of the hinged plat'- form first pulls the arm XV down far enough to release the catch XV from the stud 48, so that the voting apparatus is permitted to revolve. As soon as the catch W has been released the cam 5l striking the pin 52 causes the arm XV to release the stud 50 and permits spring 47 to pull catch W into position to engage with stud a8 again when the voting apparatus has completed its revolution. When the platform rises,the arm XV rises also, and its end rengages with the stud 50.
